The clean energy sector continues to be treacherous for investors. In my last update I had four coverage termination, one on the NASDAQ (Beacon) and 3 on OTC/venture exchanges. As I have previously commented, the OTC/venture exchanges remain very risky. There are more terminations to come in my next update as well as some new IPOs I’ll be following.
